SONIC OWNERS MANUAL

MAINTENANCE SCHEDULE
Apart from your normal pre-flight checks, and even if you have conscientiously
maintained the glider in A1 condition, more thorough checks of the glider are necessary
from time to time. If you follow the schedule faithfully, you will not only extend the
possible life of the glider, but give yourself many more hours of anxiety-free flying.
Every 10 hours:
• Check top and bottom surface battens against template.
Every 50 hours (or 6 months):
• Inspect the sail. Apply sail repair tape to any small rips or tears. Check the
stress areas of the sail, including the sail mount screw grommets and the total
length of the trailing edge. A tear or nick in the trailing edge will need
professional sail-maker repair. The reflex bridle attachment tabs, the king post
opening, and wire slots are also prone to wear under certain conditions, so
inspection here is also necessary. Any critical sail damage should be repaired by
a professional sail maker.
• Inspect all batten bungee cords and replace or re-tie where necessary.
• Inspect crossbar tensioning rigging and fittings.
• Open under-surface and crossbar plate cover and inspect crossbar ball and
socket joints, nuts, and bolts, and associated components.
• Check all tubing for dings, bends and wear damage that could occur during set-
up, breakdown or transportation.
• Inspect cables for broken strands with special attention to the thimbles and
attachment points. Check any areas with plastic coating damage more closely.
• Check that thread shows beyond all locknuts and that safety pins and rings are
serviceable and not prone to accidental opening.
Every 100 hours (or 12 months):
This annual inspection can be done by yourself but preferably your Moyes dealer or
qualified hang glider technician should be contacted to carry out this complete strip
down.
